R400 is an EPS class which can be used in production of EPS foam in density ranges above 18 kg/m3 suitable for high quality block molding with a section thickness ot 10 mm and lower
R400 is used for cases and packaging product suitable for food contact, insulation applications is not requiring fire clas-sification, in industrial application inside proton brick with impact absorber and for light concrete application.
Lower densities can be achieved after multiple expansion stages.
